过去的研究报告称，荒地与城市界面（WUI）的急剧增长，这里是人造结构与荒地植被相遇或重叠的地方。由于荒地和建筑物燃料的结合，WUI 地区的扑救工作非常困难，因此，WUI 地区的特点是经常发生山火损坏和建筑物损失。最近的荒地火灾政策主要针对 WUI 地区的防火、疏散规划、燃料处理和房屋加固。因此，了解与 WUI 位置相关的野火事件的发生非常重要。在这项工作中，我们报告了 WUI 的野火发生情况，并量化了 WUI 的面积位于加利福尼亚州复杂的地形上，这加剧了火灾行为并使灭火变得复杂。我们还分析了与WUI相关的参数，如房屋密度、植被密度和距野火的距离，以及地形因素，如坡度、高程、坡向和表面粗糙度，对WUI附近大小野火的发生以及大型野火的过火面积的相对重要性。我们发现，极小比例的野火点火点和大面积野火烧毁区域（>400 公顷或 1000 英亩）位于 WUI 地区。西UI发生了一小部分大型山火（3%），西UI面积仅占烧毁面积的4%，而在西UI以外（距西UI 5公里缓冲区），这一比例分别增加到5%和56%。同样，66% 的火灾发生在 WUI 之外，而只有 3.6% 发生在 WUI 内。这项研究的结果对燃料管理和基础设施加固以及灭火和社区响应具有重要意义。
Past studies reported a drastic growth in the wildland–urban interface (WUI), the location where man‐made structures meet or overlap wildland vegetation. Fighting fire is difficult in the WUI due to the combination of wildland and structural fuels, and therefore, WUI areas are characterized by frequent damage and loss of structures from wildfires. Recent wildland fire policy has targeted fire prevention, evacuation planning, fuel treatment, and home hardening in WUI areas. Therefore, it is important to understand the occurrence of wildfire events relative to the location of the WUI. In this work, we have reported the occurrences of wildfires with respect to the WUI and quantified how much of the WUI is on complex topography in California, which intensifies fire behavior and complicates fire suppression. We have additionally analyzed the relative importance of WUI‐related parameters, such as housing density, vegetation density, and distance to wildfires, as well as topographic factors, such as slope, elevation, aspect, and surface roughness, on the occurrence of large and small wildfires and the burned area of large wildfires near the WUI. We found that a very small percentage of wildfire ignition points and large wildfire‐burned areas (>400 ha or 1000 acres) were located in the WUI areas. A small percentage of large wildfires were encountered in WUI (3%), and the WUI area accounted for only 4% of the area burned, which increased to 5% and 56%, respectively, outside WUI (5‐km buffer from WUI). Similarly, 66% of fires ignited outside WUI, whereas only 3.6% ignited within WUI. Results from this study have implications for fuel management and infrastructure hardening, as well as for fire suppression and community response.
